Product Description
YHM’s Suppressor Gas Block is built for shooters who want an affordable way to tune an AR-style rifle dedicated to suppressed use. It uses a reduced gas port (50% smaller than a standard gas block) to help decrease “port pop” and mitigate blowback to the shooter for a more comfortable suppressed shooting experience. Because barrel gas port size, barrel length, caliber, suppressor design, and ammunition can vary widely, you may need to fine-tune the port size to match your exact setup. Constructed from 4140 steel and finished with a mil-spec phosphate coating, it’s designed for durability in hard-use applications.
